Cryogenic deflashing for injection molded rubber parts
During rubber injection molding, excess material called flash forms on the surfaces of parts. Unless this unwanted rubber is removed, surface quality suffers. In product assemblies, flash on molded components like rubber gaskets and o-rings can interfere with seating, mating and sealing. A quality injection mold and a skilled injection molder can reduce the amount of flash; but even so-called flashless molds are not immune to this common defect.
